## Ingredients You’ll Need

Here’s a list of everything you’ll need to create this delicious Ground Beef Spinach Casserole. We’ve also included some helpful notes and suggestions for substitutions.

* **Ground Beef:** 1 pound (450g). Use lean ground beef (90/10 or 93/7) to minimize grease. You can also substitute with ground turkey or ground chicken for a lighter option.
* **Spinach:** 10 ounces (280g) fresh spinach or 10 ounces (280g) frozen spinach, thawed and squeezed dry. Fresh spinach will need to be washed thoroughly and roughly chopped. Ensure frozen spinach is thoroughly squeezed to remove excess moisture; otherwise, your casserole will be watery.
* **Onion:** 1 medium, chopped. Yellow or white onion works well. For a milder flavor, you can use a sweet onion.
* **Garlic:** 2-3 cloves, minced. Freshly minced garlic provides the best flavor. You can use garlic powder (about 1 teaspoon) as a substitute, but the flavor won’t be as intense.
* **Tomato Sauce:** 1 (15 ounce) can (425g). Use plain tomato sauce or tomato sauce with basil for added flavor.
* **Diced Tomatoes:** 1 (14.5 ounce) can (410g), undrained. Diced tomatoes add texture and acidity to the casserole. You can use plain diced tomatoes or diced tomatoes with herbs.
* **Italian Seasoning:** 1 teaspoon. This blend of herbs adds a classic Italian flavor. You can also use a combination of dried oregano, basil, and thyme.
* **Salt and Pepper:** To taste. Season generously to enhance the flavors of the other ingredients.
* **Ricotta Cheese:** 15 ounces (425g). Whole milk or part-skim ricotta cheese works well. Make sure to drain any excess liquid from the ricotta before using it.
* **Egg:** 1 large. The egg helps bind the ricotta cheese together and prevents it from becoming too dry.
* **Mozzarella Cheese:** 2 cups, shredded. Use part-skim or whole milk mozzarella cheese. You can also use a blend of mozzarella and provolone cheese for a more complex flavor.
* **Parmesan Cheese:** 1/2 cup, grated. Parmesan cheese adds a salty, nutty flavor to the casserole. Use freshly grated Parmesan cheese for the best flavor.
* **Cooked Pasta or Potatoes:** 1 pound (450g). This is the base of your casserole. Elbow macaroni, penne, or rotini are all good choices. Alternatively, you can use sliced cooked potatoes (about 4 medium potatoes) for a lower-carb option. Ensure the pasta is cooked al dente to prevent it from becoming mushy in the casserole. If using potatoes, boil or bake them until tender, then slice them into rounds.

## Equipment You’ll Need

* Large skillet or pot
* 9×13 inch baking dish
* Mixing bowls
* Spatula or wooden spoon
* Cheese grater
* Can opener
* Measuring cups and spoons

## Step-by-Step Instructions

Now, let’s get started! Follow these easy steps to create your own delicious Ground Beef Spinach Casserole.

**Step 1: Prepare the Ingredients**

* Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish.
* If using fresh spinach, wash it thoroughly and roughly chop it. If using frozen spinach, thaw it and squeeze out all excess moisture. This step is crucial to prevent a watery casserole.
* Chop the onion and mince the garlic.
* Cook the pasta according to package directions until al dente. Drain well. If using potatoes, cook them until tender, let them cool slightly, and slice them into rounds.
* Grate the mozzarella and Parmesan cheese.

**Step 2: Cook the Ground Beef**

* Heat a large skillet or pot over medium-high heat.
* Add the ground beef and cook, breaking it up with a spatula or wooden spoon, until it’s browned and no longer pink. Drain off any excess grease. This step is important to prevent a greasy casserole.

**Step 3: Sauté the Vegetables**

* Add the chopped onion and minced garlic to the skillet with the cooked ground beef.
* Cook, stirring occasionally, until the onion is softened and translucent, about 5-7 minutes. This step helps to develop the flavor of the vegetables.

**Step 4: Add the Sauce and Seasonings**

* Stir in the tomato sauce, diced tomatoes, Italian seasoning, salt, and pepper.
* Bring the mixture to a simmer and cook for 5-10 minutes, stirring occasionally, to allow the flavors to meld together. Simmering the sauce enhances its richness and depth of flavor.

**Step 5: Combine the Spinach**

* Add the spinach to the skillet and stir until it’s wilted and incorporated into the sauce. If using fresh spinach, it will wilt down quickly. If using frozen spinach, make sure it’s evenly distributed throughout the mixture.

**Step 6: Prepare the Ricotta Cheese Mixture**

* In a medium mixing bowl, combine the ricotta cheese, egg, and a pinch of salt and pepper. Mix well until everything is evenly combined. The egg helps to bind the ricotta cheese and prevent it from drying out during baking.

**Step 7: Assemble the Casserole**

* Spread a thin layer of the ground beef and spinach mixture on the bottom of the greased baking dish. This will prevent the pasta or potatoes from sticking to the bottom.
* Arrange half of the cooked pasta (or sliced potatoes) over the sauce. Make sure the pasta is evenly distributed across the bottom of the dish. If using potatoes, overlap the slices slightly.
* Spread half of the ricotta cheese mixture over the pasta (or potatoes). Use a spatula or spoon to evenly spread the ricotta cheese mixture over the pasta.
* Sprinkle with one-third of the mozzarella cheese and one-third of the Parmesan cheese.
* Repeat layers: ground beef and spinach mixture, remaining pasta (or potatoes), remaining ricotta cheese mixture.
* Top with the remaining mozzarella cheese and Parmesan cheese. Make sure the cheese is evenly distributed over the top of the casserole.

**Step 8: Bake the Casserole**

* Cover the baking dish with aluminum foil. This will help to prevent the cheese from browning too quickly and keep the casserole moist.
* Bake for 20 minutes.
* Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly and the casserole is heated through. Removing the foil allows the cheese to brown and become golden brown.

**Step 9: Let it Rest and Serve**

* Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This allows the casserole to set and makes it easier to cut.
* Cut into squares and serve hot. Enjoy!

## Tips for the Perfect Casserole

* **Don’t Overcook the Pasta:** Cook the pasta al dente to prevent it from becoming mushy in the casserole.
* **Squeeze Out Excess Moisture:** Make sure to squeeze out all excess moisture from the frozen spinach to prevent a watery casserole.
* **Use Lean Ground Beef:** Using lean ground beef will minimize grease in the casserole. Drain off any excess grease after cooking the ground beef.
* **Don’t Skip the Resting Time:** Letting the casserole rest for 10-15 minutes before serving allows it to set and makes it easier to cut.
* **Adjust Seasonings to Taste:** Taste the ground beef and spinach mixture before assembling the casserole and adjust the seasonings to your liking.

## Variations and Substitutions

This Ground Beef Spinach Casserole is easily customizable to suit your dietary needs and preferences. Here are a few variations and substitutions you can try:

* **Use Ground Turkey or Chicken:** Substitute the ground beef with ground turkey or chicken for a lighter option.
* **Add Other Vegetables:** Add other vegetables to the casserole, such as mushrooms, bell peppers, or zucchini. Sauté the vegetables with the onion and garlic before adding them to the sauce.
* **Use Different Types of Cheese:** Experiment with different types of cheese, such as provolone, Monterey Jack, or cheddar cheese.
* **Make it Gluten-Free:** Use gluten-free pasta or potatoes to make this casserole gluten-free. You can also use a gluten-free cream of mushroom soup instead of the ricotta cheese mixture.
* **Add a Creamy Sauce:** Add a creamy sauce to the casserole for extra richness. You can use a can of condensed cream of mushroom soup or make a homemade béchamel sauce.
* **Make it Spicy:** Add a pinch of red pepper flakes or a dash of hot sauce to the ground beef and spinach mixture for a spicy kick.
* **Add Herbs:** Incorporate fresh herbs like basil, oregano, or parsley for a burst of flavor.
* **Use Cottage Cheese:** Substitute ricotta cheese with cottage cheese for a different texture and flavor profile.
* **Add a Breadcrumb Topping:** Sprinkle the casserole with a mixture of breadcrumbs, Parmesan cheese, and melted butter before baking for a crispy topping.

## Serving Suggestions

This Ground Beef Spinach Casserole is a complete meal on its own, but you can also serve it with a side salad or some crusty bread.

* **Side Salad:** A simple green salad with a light vinaigrette dressing complements the richness of the casserole.
* **Crusty Bread:** Serve with some crusty bread for soaking up the delicious sauce.
* **Garlic Bread:** Garlic bread is another great option for serving with this casserole.
* **Steamed Vegetables:** Serve with steamed vegetables, such as broccoli or green beans, for a healthier meal.

## Storage and Reheating Instructions

**Storage:**

* **Refrigerator:** Store leftover Ground Beef Spinach Casserole in an airtight container in the refrigerator for up to 3-4 days.
* **Freezer:** To freeze the casserole, let it cool completely before wrapping it tightly in plastic wrap and then in aluminum foil. You can also store it in a freezer-safe container. It can be frozen for up to 2-3 months. Thaw it in the refrigerator overnight before reheating.

**Reheating:**

* **Oven:** Preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover it with aluminum foil. Bake for 20-25 minutes, or until heated through. Remove the foil for the last 5 minutes to allow the cheese to melt and become bubbly.
* **Microwave:** Place a portion of the casserole on a microwave-safe plate. Cover with a paper towel and microwave on high for 1-2 minutes, or until heated through.
* **Skillet:** You can also reheat the casserole in a skillet over medium heat. Add a little bit of water or broth to the skillet to prevent it from drying out. Cook, stirring occasionally, until heated through.

## Make-Ahead Instructions

This Ground Beef Spinach Casserole is a great make-ahead meal. You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. When you’re ready to bake it, simply preheat your oven and bake according to the instructions.

For even longer storage, you can freeze the unbaked casserole. Wrap it tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 2-3 months. Thaw it in the refrigerator overnight before baking. You may need to add a few extra minutes to the baking time if baking from frozen.
